If you are using Win32lib its easy. There is an undocumented (sorry)
routine called "getEdit" that returns the id of the combobox's edit
area. You can use that to set a handler to trap keystrokes. Something
along the lines of ...

procedure keytrap(integer self, integer event, sequence parms)
      if parms[1] = VK_ESC then
         . . . 
      elsif parms[1] = VK_ENTER then
         . . .
      end if
  end procedure
  setHandler(getEdit(MyCombo), w32HKeyPress, routine_id("keytrap"))
